Protector and busbar module

Abstract

A protector includes a case unit including an accommodation chamber that accommodates an extra length portion of a flexible printed wiring board to which a connector is connected, and a guide portion extending along a sliding direction; and a slide body that includes a holding portion that holds a portion between the connector and the extra length portion in the flexible printed wiring board and moves along the sliding direction while being guided by the guide portion. The case unit and the slide body are configured to cause the extra length portion to be extended from the accommodation chamber when the slide body is moved to a first side in the sliding direction, and cause the extra length portion extending from the accommodation chamber to be accommodated in the accommodation chamber when the slide body is moved to a second side in the sliding direction.

What is claimed is: 
     
         1 . A protector comprising:
 a case unit including an accommodation chamber that accommodates an extra length portion of a flexible printed wiring board to which a connector is connected, and a guide portion extending along a sliding direction; and   a slide body that includes a holding portion that holds a portion between the connector and the extra length portion in the flexible printed wiring board, and moves along the sliding direction while being guided by the guide portion, wherein   the case unit and the slide body are configured to cause the extra length portion to be extended from the accommodation chamber when the slide body is moved to a first side in the sliding direction, and cause the extra length portion extending from the accommodation chamber to be accommodated in the accommodation chamber when the slide body is moved to a second side in the sliding direction.   
     
     
         2 . The protector according to  claim 1 , wherein
 the case unit and the slide body are configured to form a plurality of fold-back portions in the extra length portion and stack the extra length portion in the accommodation chamber.   
     
     
         3 . The protector according to  claim 2 , wherein
 the case unit includes a supporting portion that forms a first fold-back portion in the extra length portion and supports the first fold-back portion from inside, and   the first fold-back portion has a fold-back shape convex toward the first side.   
     
     
         4 . The protector according to  claim 2 , wherein
 the slide body holds the flexible printed wiring board by the holding portion so as to form a second fold-back portion in the extra length portion, and   the second fold-back portion has a fold-back shape convex toward the second side.   
     
     
         5 . A busbar module comprising:
 the protector according to  claim 1 ;   the flexible printed wiring board;   the connector connected to the flexible printed wiring board; and   a plurality of busbars connected to the flexible printed wiring board and connectable to an electrode of a battery cell.
